INSTALLATION NOTES for OpenBSD/mvme88k 5.5 What is OpenBSD? ---------------- OpenBSD is a fully functional, multi-platform UN*X-like Operating System based on Berkeley Networking Release 2 (Net/2) and 4.4BSD-Lite. There are several operating systems in this family, but OpenBSD differentiates itself by putting security and correctness first. The OpenBSD team strives to achieve what is called a 'secure by default' status. This means that an OpenBSD user should feel safe that their newly installed machine will not be compromised. This 'secure by default' goal is achieved by taking a proactive stance on security. Since security flaws are essentially mistakes in design or implement- ation, the OpenBSD team puts as much importance on finding and fixing existing design flaws and implementation bugs as it does writing new code. This means that an OpenBSD system will not only be more secure, but it will be more stable. The source code for all critical system components has been checked for remote-access, local-access, denial- of-service, data destruction, and information-gathering problems. In addition to bug fixing, OpenBSD has integrated strong cryptography into the base system. A fully functional IPsec implementation is provided as well as support for common protocols such as SSL and SSH. Network filtering and monitoring tools such as packet filtering, NAT, and bridging are also standard, as well as several routing services, such as BGP and OSPF. For high performance demands, support for hardware cryptography has also been added to the base system. Because security is often seen as a tradeoff with usability, OpenBSD provides as many security options as possible to allow the user to enjoy secure computing without feeling burdened by it. Because OpenBSD is from Canada, the export of Cryptography pieces (such as OpenSSH, IPsec, and Kerberos) to the world is not restricted. (NOTE: OpenBSD can not be re-exported from the US once it has entered the US. Because of this, take care NOT to get the distribution from an FTP server in the US if you are outside of Canada and the US.) A comprehensive list of the improvements brought by the 5.5 release is available on the web at http://www.OpenBSD.org/55.html. OpenBSD/mvme88k runs on the Motorola 88100 and 88110 processor-based VME boards and systems built upon them. Sources of OpenBSD: ------------------- Please refer to http://www.openbsd.org/ftp.html for all the ways you may acquire OpenBSD. OpenBSD 5.5 Release Contents: ----------------------------- The OpenBSD 5.5 release is organized in the following way. In the .../5.5 directory, for each of the architectures having an OpenBSD 5.5 binary distribution, there is a sub-directory. The mvme88k-specific portion of the OpenBSD 5.5 release is found in the "mvme88k" subdirectory of the distribution. That subdirectory is laid out as follows: .../5.5/mvme88k/ INSTALL.mvme88k Installation notes; this file. SHA256 Output of the sum(1) program using the option -a sha256, usable for verification of the correctness of downloaded files. SHA256.sig The above file, signed with the OpenBSD signing key for the 5.5 release, usable for verification of the integrity of the above file, and thus of the downloaded files. *.tgz mvme88k binary distribution sets; see below. bsd A stock GENERIC mvme88k kernel which will be installed on your system during the install. bsd.mp A stock GENERIC.MP mvme88k kernel, with support for multiprocessor machines, which can be used instead of the GENERIC kernel after the install. bsd.rd A compressed RAMDISK kernel; the embedded filesystem contains the installation tools. Used for simple installation from a pre-existing system. installboot The OpenBSD/mvme88k boot loader installation program. bootxx The OpenBSD/mvme88k boot block. bootsd The OpenBSD/mvme88k disk boot loader. bootst The OpenBSD/mvme88k tape boot loader. netboot The OpenBSD/mvme88k Sun-compatible network boot loader. sboot The OpenBSD/mvme88k Sun-compatible network boot loader, in S-records format. stboot A VID tape block, to be used with the tape boot loader. tftpboot The OpenBSD/mvme88k tftp-compatible network boot loader. These files can be used to make a bootable tape suitable for installation. They can also be used to configure an NFS server to support installation over the network. See the section "Getting the OpenBSD system onto Useful Media" for more information. The OpenBSD/mvme88k binary distribution sets contain the binaries which comprise the OpenBSD 5.5 release for mvme88k systems. There are ten binary distribution sets. The binary distribution sets can be found in the "mvme88k" subdirectory of the OpenBSD 5.5 distribution tree, and are as follows: base55 The OpenBSD/mvme88k 5.5 base binary distribution. You MUST install this distribution set. It contains the base OpenBSD utilities that are necessary for the system to run and be minimally functional. It includes shared library support, and excludes everything described below. [ 61.5 MB gzipped, 176.4 MB uncompressed ] comp55 The OpenBSD/mvme88k Compiler tools. All of the tools relating to C, C++ and Objective-C are supported. This set includes the system include files (/usr/include), the linker, the compiler tool chain, and the various system libraries (except the shared libraries, which are included as part of the base set). This set also includes the manual pages for all of the utilities it contains, as well as the system call and library manual pages. [ 88.7 MB gzipped, 247.9 MB uncompressed ] etc55 This distribution set contains the system configuration files that reside in /etc and in several other places. This set MUST be installed if you are installing the system from scratch, but should NOT be used if you are upgrading. (If you are upgrading, it's recommended that you get a copy of this set and CAREFULLY upgrade your configuration files by hand; see the section named "Upgrading a previously-installed OpenBSD System" below.) [ 513.8 KB gzipped, 1.6 MB uncompressed ] game55 This set includes the games and their manual pages. [ 2.5 MB gzipped, 5.7 MB uncompressed ] man55 This set includes all of the manual pages for the binaries and other software contained in the base set. Note that it does not include any of the manual pages that are included in the other sets. [ 9.4 MB gzipped, 36.5 MB uncompressed ] xbase55 This set includes the base X distribution. This includes programs, headers and libraries. [ 11.6 MB gzipped, 30.2 MB uncompressed ] xetc55 This set includes the X window system configuration files that reside in /etc. It's the equivalent of etc55 for X. [ 63.4 KB gzipped, 266.1 KB uncompressed ] xfont55 This set includes all of the X fonts. [ 38.0 MB gzipped, 49.7 MB uncompressed ] xserv55 This set includes all of the X servers. [ 1.5 MB gzipped, 3.6 MB uncompressed ] xshare55 This set includes all text files equivalent between all architectures. [ 4.2 MB gzipped, 23.2 MB uncompressed ] OpenBSD System Requirements and Supported Devices: -------------------------------------------------- OpenBSD/mvme88k 5.5 runs on the systems built around the following MVME boards: - MVME181 (Barebone system with 88100 processor) - MVME187/M8120 (Single board computer with 88100 processor) - MVME188 (HYPERmodule-based systems with up to 4 88100 processors) - MVME197LE (Single board computer with 88110 processor) - MVME197SP/DP (Single board computer with up to two 88110 processors) Besides various Motorola complete systems (M8120, Series 900, etc), OpenBSD/mvme88k also runs on the MVME187-based Triton Dolphin System 100. OpenBSD/mvme88k 5.5 supports MVME188 and MVME197DP SMP (Symmetrical MultiProcessor) systems. To support SMP operation, a separate SMP kernel (bsd.mp) is included with the installation file sets. While OpenBSD will boot single-user in 8MB, a minimum of 12MB of RAM is necessary to install and boot multi-user, and 16MB of RAM are recommended as a minimum for the system not to be swap-bound, with 32MB or more being recommended for serious usage of the system. A minimal system can probably be squeezed onto a 250MB disk by installing only the `base' and `etc' sets and using a small swap partition. Note that until you have at least 32MB of RAM, getting more RAM is more important than getting a faster CPU board. Supported HYPERmodules: (for MVME188 systems) 1P32 (1 88100 processor, 2 88200 CMMUs, similar to MVME187) 1P64 (1 88100 processor, 4 88200 CMMUs) 1P128 (1 88100 processor, 8 88200 CMMUs, untested) 1P128 (1 88100 processor, 2 88204 CMMUs) 1P256 (1 88100 processor, 4 88204 CMMUs) 1P512 (1 88100 processor, 8 88204 CMMUs, untested) 2P64 (2 88100 processors, 4 88200 CMMUs) 2P128 (2 88100 processors, 8 88200 CMMUs) 2P256 (2 88100 processors, 4 88204 CMMUs) 2P512 (2 88100 processors, 8 88204 CMMUs) 4P128 (4 88100 processors, 8 88200 CMMUs) 4P512 (4 88100 processors, 8 88204 CMMUs) Supported devices: MVME181 on-board devices: serial ports, ttya-ttyb (dart) MVME181 compatible VME memory boards: MVME224 and MVME224A (4, 8, 16 and 32MB) MVME236 (4, 8 and 16MB) MVME187, M8120 and MVME197 on-board devices: Cirrus Logic CD2401 serial ports (cl) Intel 82596CA Ethernet (ie) NCR53c710 SCSI Controller (osiop) 128KB SRAM (/dev/sram0) 8KB NVRAM (/dev/nvram0) MVME188 on-board devices: serial ports on SYSCON board (dart) 2KB NVRAM (/dev/nvram0) Additional VMEbus devices: MVME327A SCSI and floppy Controller (vsbic), currently limited to the SCSI interface only MVME328 High Performance SCSI Controller (vs) MVME376 Ethernet Communications Controller (le) Getting the OpenBSD System onto Useful Media: --------------------------------------------- Installation is supported from several media types, including: CD-ROM FFS partitions Tape Remote NFS partition FTP HTTP The steps necessary to prepare the distribution sets for installation depend on which method of installation you choose. Some methods require a bit of setup first that is explained below. The installation allows installing OpenBSD directly from FTP mirror sites over the internet, however you must consider the speed and reliability of your internet connection for this option. It may save much time and frustration to use ftp get/reget to transfer the distribution sets to a local server or disk and perform the installation from there, rather than directly from the internet. The variety of options listed may seem confusing, but situations vary widely in terms of what peripherals and what sort of network arrangements a user has, the intent is to provide some way that will be practical. Creating an (optionally bootable) installation tape: To install OpenBSD from a tape, you need to make a tape that contains the distribution set files, each in "tar" format or in "gzipped tar format". First you will need to transfer the distribution sets to your local system, using ftp or by mounting the CD-ROM containing the release. Then you need to make a tape containing the files. If you're making the tape on a UN*X-like system, the easiest way to do so is make a shell script along the following lines, call it "/tmp/maketape". #! /bin/sh TAPE=${TAPE:-/dev/nrst0} mt -f ${TAPE} rewind if test $# -lt 1 then dd of=${TAPE} if=stboot obs=512 dd of=${TAPE} if=bootst obs=512 dd of=${TAPE} if=bsd.rd obs=8k conv=osync fi for file in base etc comp game man xbase xetc xfont xserv xshare do dd if=${file}55.tgz of=${TAPE} obs=8k conv=osync done tar cf ${TAPE} bsd mt -f ${TAPE} offline # end of script And then: cd .../5.5/mvme88k sh -x /tmp/maketape Note that, by default, this script creates a bootable tape. If you only want to fetch the OpenBSD files from tape, but want to boot from another device, you can save time and space creating the tape this way: cd .../5.5/mvme88k sh -x /tmp/maketape noboot If you're using a system other than OpenBSD, the tape name and other requirements may change. You can override the default device name (/dev/nrst0) with the TAPE environment variable. For example, under Solaris, you would probably run: TAPE=/dev/rmt/0n sh -x /tmp/maketape Note that, when installing, the tape can be write-protected (i.e. read-only). To install OpenBSD using a remote partition, mounted via NFS, you must do the following: NOTE: This method of installation is recommended only for those already familiar with using BSD network configuration and management commands. If you aren't, this documentation should help, but is not intended to be all-encompassing. Place the OpenBSD distribution sets you wish to install into a directory on an NFS server, and make that directory mountable by the machine on which you are installing or upgrading OpenBSD. This will probably require modifying the /etc/exports file of the NFS server and resetting its mount daemon (mountd). (Both of these actions will probably require superuser privileges on the server.) You need to know the numeric IP address of the NFS server, and, if the server is not on a network directly connected to the machine on which you're installing or upgrading OpenBSD, you need to know the numeric IP address of the router closest to the OpenBSD machine. Finally, you need to know the numeric IP address of the OpenBSD machine itself. Once the NFS server is set up properly and you have the information mentioned above, you can proceed to the next step in the installation or upgrade process. If you are upgrading OpenBSD, you also have the option of installing OpenBSD by putting the new distribution sets somewhere in your existing file system, and using them from there. To do that, do the following: Place the distribution sets you wish to upgrade somewhere in your current file system tree. At a bare minimum, you must upgrade the "base" binary distribution, and so must put the "base55" set somewhere in your file system. It is recommended that you upgrade the other sets, as well. Preparing your System for OpenBSD Installation: ----------------------------------------------- Before installing OpenBSD on your machine, you will want to check your machine's NVRAM settings, from the BUG. The BUG provides a simple syntax reminder for every command, as well as a description of the commands; if you need help, just use 187-Bug> HE for a command list, or 187-Bug> HE FOO for help on a specific command. If you are located in the diagnostics directory (with a prompt in -Diag> rather than -Bug>), be sure to revert to the normal Bug operating mode with the SD command: 187-Diag> SD 187-Bug> The default settings are usually suitable for OpenBSD; make sure the environment is configured in BUG mode. You can check and change this with the ENV command. Ideally, the first two items of the ENV data will be as follows: 187-Bug> ENV Bug or System environment [B/S] = B? Field Service Menu Enable [Y/N] = N? in order to boot directly into the BUG, without executing the complete selftest sequence. Do not forget, after changing the ENV parameters, to save the changes in NVRAM as suggested by the ENV command itself. If the board has a built-in Ethernet controller, its address must be correct; the LSAD command allows the address to be edited. OpenBSD/mvme88k will not run correctly if the clock is stopped (power-saving mode). Be sure to check that it is running by setting the current date with the SET command. If you plan to permanently boot from the network, make sure your ENV settings match the following setup: Network Auto Boot Enable [Y/N] = N? Y Network Auto Boot at power-up only [Y/N] = Y? N Network Auto Boot Abort Delay = 5? 2 (or any value at your choice) Network Auto Boot Configuration Parameters Pointer (NVRAM) = 00000000? FFFC0080 Installing the OpenBSD System: ------------------------------ Installing OpenBSD is a relatively simple process. If you take your time and are careful to read the information presented by the installer, you shouldn't have any trouble. There are several ways to install OpenBSD onto a disk. The easiest way in terms of preliminary setup is to use the OpenBSD ramdisk kernel that can be booted from tape. Alternatively, if the mvme88k is hooked up to a network, it is possible to set up another machine as a server for diskless setup, which is a convenient way to install on a machine whose disk does not currently hold a usable operating system. This is difficult to get set up correctly the first time, but easy to use afterwards. (See ``Installing using a diskless setup'' below). Boot device restrictions: The BUG firmware will not necessarily be able to boot from any device in the system. Depending on the BUG firmware version, the following limitations may apply: - bootable SCSI tapes must have device ID 4 or 5. - bootable SCSI disks must have device ID 0, 1, 2 or 3. - only the first two MVME328 cards in a system (CLUN 6 and 7) can be used as the boot controller. Booting from the Installation Media: Prior to attempting an installation, everything of value on the target system should be backed up. While installing OpenBSD does not necessarily wipe out all the partitions on the hard disk, errors during the install process can have unforeseen consequences and will probably leave the system unbootable if the installation process is not completed. Availability of the installation media for the prior installation, such as a Motorola SystemV/mvme88k tape is always a good insurance, should it be necessary to "go back" for some reason. After taking care of all that, the system should be brought down gracefully using the shutdown(8) and/or halt(8) commands, which will eventually go back to the ``BUG>'' prompt (it may be necessary to send a break if the system is completely halted). Booting from SCSI tape: Bootable tapes can be booted with the following command at the prompt: 187-Bug> BO xx yy Where `xx' is the SCSI controller number (00 for the built-in SCSI controller on MVME187 and MVME197), and `yy' is the encoding for the SCSI device ID, which varies between controllers. Recent BUG can list the available disk and tape controllers, using the "IOT;H" command: 187-Bug>IOT;H I/O Controllers Available: CLUN CNTRL-TYPE CNTRL-Address N-Devices 0 VME187 $FFF47000 * 6 VME328 $FFFF9000 * In this example, the built-in controller, as well as an external MVME328 controller, are available. The encoding for the drive ID is as follows: - MVME187 and MVME197 built-in controller and MVME327A SCSI controller: 'yy' is ten times the device ID. - MVME328 SCSI controller: 'yy' is eight times the device ID, written in hexadecimal - MVME350 tape controller: 'yy' is always zero, as this controller only supports one tape drive. For example, booting from a tape drive using SCSI ID #5 will be done with: 187-Bug> BO 00 50 using the MVME187 built-in controller, but with: 187-Bug> BO 06 28 using an MVME328 board. Note that OpenBSD/mvme88k can boot off any controller supported by the BUG, even if it is not supported by OpenBSD. Booting from Network: OpenBSD/mvme88k can boot off any network card supported by the BUG, even if the card itself is not supported by OpenBSD. Two network boot loaders are provided: one for Sun-compatible diskless setup (bootparams and NFS root), and a simpler version limited to TFTP support. The Sun-compatible network bootloader currently only supports the MVME187 and MVME197 on-board interface, as well as MVME376 boards. It will not be able to boot from any other Ethernet controller (such as MVME374). On systems lacking network support in the BUG, the Sun-compatible network bootloader may be loaded as S-Records. The tftp bootloader can only be used with a network boot capable BUG, and will boot from any BUG-supported Ethernet controller. If you plan to use the Sun-compatible bootloader, "netboot", it will be necessary to set up a complete diskless client configuration on a server. If the boot server is an OpenBSD system, the diskless(8) manual page will provide detailed information on the process. If the server runs another operating system, the setup instructions will likely be available as part of the documentation that came with it (on SunOS systems, add_client(8) and the Sun System/Networks administrators guide constitute a good start; on Solaris systems, share(1M) is a good starting point as well). Using the TFTP-compatible bootloader, "tftpboot", only requires a TFTP server to be installed on the network, with both the tftpboot file and the kernel image (usually bsd.rd) available from it. The list of BUG-supported Ethernet controllers is available with the "NIOT;A" command. For example: 187-Bug> NIOT;A Network Controllers/Nodes Supported CLUN DLUN Name Address 0 0 VME187 $FFF46000 2 0 VME376 $FFFF1200 3 0 VME376 $FFFF1400 4 0 VME376 $FFFF1600 5 0 VME376 $FFFF5400 6 0 VME376 $FFFF5600 7 0 VME376 $FFFFA400 10 0 VME374 $FF000000 11 0 VME374 $FF100000 12 0 VME374 $FF200000 13 0 VME374 $FF300000 14 0 VME374 $FF400000 15 0 VME374 $FF500000 The "NIOT;H" lists only the available controllers in the machine. For example, on an MVME187 system with no external network card: 187-Bug> NIOT;H Network Controllers/Nodes Available CLUN DLUN Name Address 0 0 VME187 $FFF46000 If the BUG does not support the NIOT command (MVME187 BUG prior to version 1.3 doesn't), then it has no support for netbooting, and you'll have to use the S-Records bootloader, described later in this document. If you know the IP address for the mvme88k and the TFTP server, you can directly provide the boot loader's filename and the kernel name on the commandline: 187-Bug> NBO 00 00 192.168.0.68 192.168.0.1 netboot.mvme88k bsd.rd or 187-Bug> NBO 00 00 192.168.0.68 192.168.0.1 tftpboot.mvme88k bsd.rd where, in this example, 192.168.0.68 is the address of the mvme88k computer, and 192.168.0.1 the address of the diskless server. Specifying both IP addresses as 0.0.0.0 will cause them to be obtained with reverse ARP (for the mvme88k address) and bootp or dhcp (for the server address): 187-Bug> NBO 00 00 0.0.0.0 0.0.0.0 netboot.mvme88k bsd.rd or 187-Bug> NBO 00 00 0.0.0.0 0.0.0.0 tftpboot.mvme88k bsd.rd If you intend to netboot very often, these parameters can be made permanent by filling the "NIOT" parameters and save them to NVRAM. Be sure to provide the correct values for Controller LUN and Device LUN (as listed in the "NIOT;H" output); also the "Boot File Load Address" and "Boot File Execution Address" need to match (there is no reason to change the default value of 001F0000). The "Boot File Name" must match the name of the netboot file on the server (copying it as "netboot.mvme88k" or "tftpboot.mvme88k" is usually a wise choice). Finally, "Argument File Name" needs to be set to the kernel name: "bsd.rd" in order to boot the installation kernel, or "bsd" for the regular kernel. Here are acceptable values for a 187 card using the built-in controller: 187-Bug> NIOT Controller LUN =00? Device LUN =00? Node Control Memory Address =01FF0000? Client IP Address =0.0.0.0? Server IP Address =0.0.0.0? Subnet IP Address Mask =255.255.255.0? Broadcast IP Address =255.255.255.255? Gateway IP Address =0.0.0.0? Boot File Name ("NULL" for None) =? netboot.mvme88k Argument File Name ("NULL" for None) =? bsd.rd Boot File Load Address =001F0000? Boot File Execution Address =001F0000? Boot File Execution Delay =00000000? Boot File Length =00000000? Boot File Byte Offset =00000000? BOOTP/RARP Request Retry =00? TFTP/ARP Request Retry =00? Trace Character Buffer Address =00000000? BOOTP/RARP Request Control: Always/When-Needed (A/W)=W? BOOTP/RARP Reply Update Control: Yes/No (Y/N) =Y? If you change the NIOT configuration, you will be asked whether you want to make these changes permanent. Do not answer Y unless you plan to netboot this board very often; be sure to have the ENV settings use a correct address for the NIOT parameters block in this case. A valid setting is: Network Auto Boot Configuration Parameters Pointer (NVRAM) = 00000000? FFFC0080 for example. Once the NIOT parameters are set, it should be possible to boot the machine from the server with a shortened NBO command: 187-Bug> NBO 00 00 Booting from S-Records: If you plan to use the S-Records bootloader, "sboot", it will be necessary to set up a complete diskless client configuration on a server. Refer to the short description above for details. Using a terminal emulator able to read files from the local machine and send their contents over the serial link, such as cu(1) and tip(1) - both being available on OpenBSD - the mvme88k workstation should be put in S-Records receive mode, with the LO command followed by the serial port where S-Records are to be received (usually 0 for the console port) at the BUG prompt: 188-Bug> LO 0 Then, then contents of the ``sboot'' file should be sent from the terminal emulator (using tip(1) or cu(1), this is done by entering ``~$'', and then, at the ``Local command?'' prompt, ``cat sboot''). This operation will take a significant time: at the default 9600 bps speed, sending the S-Records take almost three minutes. If a prompt does not come back after a few minutes, it is likely that the S-Records download is hosed. In this case, the mvme88k board should be reset before a further attempt to download the S-Records is made. Once the transfer is finished, entering `GO' at the BUG prompt will start the S-Records boot loader. It will list the available network interfaces and will prompt for a filename to boot: 188-Bug>GO Effective address: 00680000 >> OpenBSD/mvme88k sboot [1.1] Network Controllers/Nodes Supported Driver CLUN DLUN Name Address Ethernet Address le0 2 0 VME376 $ffff1200 00:00:77:83:ac:56 le1 3 0 VME376 $ffff1400 00:00:77:83:83:ce boot: By default, the first interface listed will be used. To boot off a different interface, simply prefix the filename with the interface driver name (first column in the interface display), followed by a colon. For example, to boot `bsd.rd' from the second interface, one should enter: boot: le1:bsd.rd This will cause the usual Sun-compatible netboot processing to use the `le1' interface: boot: client IP address: 10.0.1.138 boot: client name: bourbouillou root addr=10.0.1.1 path=/netboot/bourbouillou/root 3262752+389824 [52+70512+58011]=0x39b394 Start @ 0x10000 Controller Address 0xffff1400 ... Installing using the tape or netboot procedure: You should now be ready to install OpenBSD. The following is a walk-through of the steps you will take while getting OpenBSD installed on your hard disk. The installation procedure is designed to gather as much information about your system setup as possible at the beginning, so that no human interaction is required as soon as the questions are over. The order of these questions might be quite disconcerting if you are used to other installation procedures, including older OpenBSD versions. If any question has a default answer, it will be displayed in brackets ("[]") after the question. If you wish to stop the installation, you may hit Control-C at any time, but if you do, you'll have to begin the installation process again from scratch. Using Control-Z to suspend the process may be a better option, or at any prompt enter `!' to get a shell, from which 'exit' will return you back to that prompt (no refresh of the prompt will occur, though). Boot your machine from the installation media as described above. It will take a while to load the kernel especially from a slow network connection, most likely more than a minute. If some action doesn't eventually happen, or the spinning cursor has stopped and nothing further has happened, either your boot media is bad, your diskless setup isn't correct, or you may have a hardware or configuration problem. Once the kernel has loaded, you will be presented with the OpenBSD kernel boot messages which contain information about the hardware that was detected and supported by OpenBSD. After the kernel is done initialising, you will be asked whether you wish to do an "(A)utoinstall", "(I)nstall" or an "(U)pgrade". Enter 'I' for a fresh install or 'U' to upgrade an existing installation. Enter 'A' to start an unattended installation where all of your answers are supplied in a response file (more on that in "Preparing an unattended installation of OpenBSD"). You will next be asked for your terminal type. You should choose the terminal type from amongst those listed. (If your terminal type is xterm, just use vt220). The first question you will be asked is the system hostname. Reply with the name of the system, without any domain part. You will now be given an opportunity to configure the network. The network configuration you enter (if any) can then be used to do the install from another system using HTTP or FTP, and will also be the configuration used by the system after the installation is complete. The install program will give you a list of network interfaces you can configure. For each network interface you select to configure, you will be asked for: - the symbolic host name to use (except for the first interface setup, which will reuse the host name entered at the beginning of the installation). - the IPv4 settings: address and netmask. If the IP address should be obtained from a DHCP server, simply enter ``dhcp'' when asked for the address. - the IPv6 settings (address, prefix length, and default router). You may enter ``rtsol'' when asked for the address for the interface to configure automatically via router solicitation messages. After all interfaces have been configured, if there have been any IPv4 interfaces setup, you will be asked for the IPv4 default route. This step is skipped if you only have one IPv4 interface setup, and it is configured with DHCP. The install program will also ask you for your DNS domain name, and the domain name servers, unless this information has already been obtained from a DHCP server during interface setup. You will also be presented with an opportunity to do more manual configuration. If you accept, you will be dropped to a shell; when you are done, enter `exit' to return to the installation program. You will then be asked to enter the initial root password of the system, twice. Although the install program will only check that the two passwords match, you should make sure to use a strong password. As a minimum, the password should be at least eight characters long and a mixture of both lower and uppercase letters, numbers and punctuation characters. You will then be asked whether you want to start sshd(8) by default, as well as ntpd(8). If you choose to start ntpd(8), you will be asked for your ntp server; if you don't have any preferred ntp server, press enter to confirm the default setting of using the pool.ntp.org servers. You will now be given the possibility to setup a user account on the forthcoming system. This user will be added to the `wheel' group. Enter the desired login name, or `n' if you do not want to add a user account at this point. Valid login names are sequences of digits and lowercase letters, and must start with a lowercase letter. If the login name matches this criteria, and doesn't conflict with any of the administrative user accounts (such as `root', `daemon' or `ftp'), you will be prompted with the users descriptive name, as well as its password, twice. As for the root password earlier, the install program will only check that the two passwords match, but you should make sure to use a strong password here as well. If you have chosen to setup a user account, and you had chosen to start sshd(8) on boot, you will be given the possibility to disable sshd(8) logins as root. The installation program will now tell you which disks it can install on, and ask you which it should use. Reply with the name of your root disk. You will the be asked if you want to use DUID notation in /etc/fstab, instead of traditional device names. You are strongly advised to use DUIDs, as they allow you to move your disks to different controllers, or change their bus identifiers, without having to modify /etc/fstab every time your configuration changes. Next the disk label which defines the layout of the OpenBSD partitions must be set up. Each file system you want will require a separate partition. You will be proposed a default partition layout, trying to set up separate partitions, disk size permitting. You will be given the possibility to either accept the proposed layout, or edit it, or create your own custom layout. These last two choices will invoke the disklabel(8) interactive editor, allowing you to create your desired layout. Within the editor, you will probably start out with only the 'c' partition of fstype 'unused' that represents the whole disk. This partition can not be modified. You must create partition 'a' as a native OpenBSD partition, i.e. one with "4.2BSD" as the fstype, to hold the root file system. In addition to partition 'a' you should create partition 'b' with fstype "swap", and native OpenBSD partitions to hold separate file systems such as /usr, /tmp, /var, and /home. You will need to provide a mount point for all partitions you define. Partitions without mount points, or not of 4.2BSD fstype, will neither be formatted nor mounted during the installation. For quick help while in the interactive editor, enter '?'. The `z' command (which deletes all partitions and starts with a clean label), the `A' command (which performs the automatic partition layout) and the `n' command (to change mount points) are of particular interest. Although the partitions position and size are written in exact sector values, you do not need a calculator to create your partitions! Human-friendly units can be specified by adding `k', `m' or `g' after any numbers to have them converted to kilobytes, megabytes or gigabytes. Or you may specify a percentage of the disk size using `%' as the suffix. Enter 'M' to view the entire manual page (see the info on the ``-E'' flag). To exit the editor enter 'q'. After the layout has been saved, new filesystems will be created on all partitions with mount points. This will DESTROY ALL EXISTING DATA on those partitions. After configuring your root disk, the installer will return to the list of available disks to configure. You can choose the other disks to use with OpenBSD in any order, and will get to setup their layout similarly to the root disk above. However, for non-root disks, you will not be proposed a default partition layout. When all your disks are configured, simply hit return at the disk prompt. After these preparatory steps have been completed, you will be able to extract the distribution sets onto your system. There are several install methods supported: FTP, HTTP, CD-ROM, tape, NFS, or a local disk partition. To install via FTP or HTTP: To begin an FTP or HTTP install you will need the following pieces of information: 1) Proxy server URL if you are using a URL-based FTP or HTTP proxy (squid, CERN FTP, Apache 1.2 or higher). You need to define a proxy if you are behind a firewall that blocks outgoing FTP or HTTP connections (assuming you have a proxy available to use). 2) The IP address (or hostname if you configured DNS servers earlier in the install) of an FTP or HTTP server carrying the OpenBSD 5.5 distribution. The installation program will try to fetch a list of such servers; depending on your network settings, this might fail. If the list could be fetched, it will be displayed, and you can choose an entry from the list (the first entries are expected to be the closest mirrors to your location). 3) The directory holding the distribution sets. The default value of pub/OpenBSD/5.5/mvme88k is almost always correct on FTP servers; for HTTP servers there is no standard location for this. 4) For FTP installs only, the login and password for the FTP account. You will only be asked for a password for non-anonymous FTP. Then refer to the section named "installation set selection" below. To install from CD-ROM: When installing from a CD-ROM, you will be asked which device holds the distribution sets. This will typically be "cd0". If there is more than one partition on the CD-ROM, you will be asked which partition the distribution is to be loaded from. This is normally partition "a". You will also have to provide the relative path to the directory on the CD-ROM which holds the distribution, for the mvme88k this is "5.5/mvme88k". Then refer to the section named "installation set selection" below. To install from an NFS mounted directory: When installing from an NFS-mounted directory, you must have completed network configuration above, and also set up the exported file system on the NFS server in advance. First you must identify the IP address of the NFS server to load the distribution from, and the file system the server expects you to mount. The install program will also ask whether or not TCP should be used for transport (the default is UDP). Note that TCP only works with newer NFS servers. You will also have to provide the relative path to the directory on the file system where the distribution sets are located. Note that this path should not be prefixed with a '/'. Then refer to the section named "installation set selection" below. To install from a local disk partition: When installing from a local disk partition, you will first have to identify which disk holds the distribution sets. This is normally "sdN", where N is a number. Next you will have to identify the partition within that disk that holds the distribution; this is a single letter between 'a' and 'p'. You will also have to identify the type of file system residing in the partition identified. Currently, you can only install from partitions that have been formatted as the Berkeley fast file system (ffs). You will also have to provide the relative path to the directory on the file system where the distribution sets are located. Note that this path should not be prefixed with a '/'. Then refer to the next section. To install from tape: Unlike all other installation methods, there is no way to know the names of the files on tape. Because of this, it is impossible to check that the files on tape match the machine architecture and release of OpenBSD/mvme88k. Moreover, since tape filenames are not known, the file checksums can not be verified. Use this installation method only if there is no better option. In order to install from tape, the distribution sets to be installed must have been written to tape previously, either in tar format or gzip-compressed tar format. You will also have to identify the tape device where the distribution sets are to be extracted from. This will typically be "nrst0" (no-rewind, raw interface). Next you will have to specify how many files have to be skipped on the tape. This number is usually zero, unless you have created a bootable tape, in which case the number will be 3. The install program will not automatically detect whether an image has been compressed, so it will ask for that information before starting the extraction of each file. Installation set selection: A list of available distribution sets found on the given location will be listed. You may individually select distribution sets to install, by entering their name, or wildcards (e.g. `*.tgz' or `base*|comp*', or `all' to select all the sets (which is what most users will want to do). You may also enter `abort' to deselect everything and restart the selection from scratch, or unselect sets by entering their name prefixed with `-' (e.g. `-x*'). It is also possible to enter an arbitrary filename and have it treated as a file set. When you are done selecting distribution sets, enter `done'. The files will begin to extract. After the files have been extracted, you will be given the choice to select a new location from which to install distribution sets. If there have been errors extracting the sets from the previous location, or if some sets have been missing, this allows you to select a better source. Also, if the installation program complains that the distribution sets you have been using do not match their recorded checksums, you might want to check your installation source (although this can happen between releases, if a snapshot is being updated on an FTP or HTTP server with newer files while you are installing). The last thing you'll need to configure is the time zone your system will be using. For this to work properly, it is expected that you have installed at least the "base55", "etc55", and "bsd" distribution sets. The installation program will then proceed to save the system configuration, create all the device nodes needed by the installed system, and will install bootblocks on the root disk. On multiprocessor systems, if the bsd.mp kernel has been installed, it will be renamed to `bsd', which is the default kernel the boot blocks look for. The single processor kernel, `bsd', will be available as `bsd.sp'. Finally, you will be asked whether you would like to install non-free firmware files (which can't be tightly integrated to the OpenBSD system) on first boot, by invoking fw_update(8) on the next boot. Congratulations, you have successfully installed OpenBSD 5.5. When you reboot into OpenBSD, you should log in as "root" at the login prompt. You should create yourself an account and protect it and the "root" account with good passwords. The install program leaves root an initial mail message. We recommend you read it, as it contains answers to basic questions you might have about OpenBSD, such as configuring your system, installing packages, getting more information about OpenBSD, sending in your dmesg output and more. To do this, run mail and then just enter "more 1" to get the first message. You quit mail by entering "q". Some of the files in the OpenBSD 5.5 distribution might need to be tailored for your site. We recommend you run: man afterboot which will tell you about a bunch of the files needing to be reviewed. If you are unfamiliar with UN*X-like system administration, it's recommended that you buy a book that discusses it. Net Boot or Diskless Setup Information: The set up is similar to SunOS diskless setup, but not identical, because the Sun setup assumes that the bootblocks load a kernel image, which then uses NFS to access the exported root partition, while the OpenBSD bootblocks use internal NFS routines to load the kernel image directly from the exported root partition. Please understand that no one gets this right the first try, since there is a lot of setup and all the host daemons must be running and configured correctly. If you have problems, extract the diskless(8) manpage, find someone who's been through it before and use the host syslog and tcpdump(8) to get visibility of what's happening (or not). Your mvme88k expects to be able to download a second stage bootstrap program via TFTP after having acquired its IP address through RevARP when instructed to boot "over the net". It will look for the filename specified on the NBO commandline, or via the NIOT parameters. Normally, this file is a symbolic link to an appropriate second-stage boot program, which should be located in a place where the TFTP daemon can find it (remember, many TFTP daemons run in a chroot'ed environment). You can find the boot program in `/usr/mdec/netboot' in the OpenBSD/mvme88k distribution. After the boot program has been loaded into memory and given control by the BUG, it starts locating the machine's remote root directory through the BOOTPARAM protocol. First a BOOTPARAM WHOAMI request is broadcast on the local net. The answer to this request (if it comes in) contains the client's name. This name is used in the next step, a BOOTPARAM GETFILE request -- sent to the server that responded to the WHOAMI request -- requesting the name and address of the machine that will serve the client's root directory, as well as the path of the client's root on that server. Finally, this information (if it comes in) is used to issue a REMOTE MOUNT request to the client's root filesystem server, asking for an NFS file handle corresponding to the root filesystem. If successful, the boot program starts reading from the remote root filesystem in search of the kernel which is then read into memory. Unpack `base55.tgz' and `etc55.tgz' on the server in the root directory for your target machine. If you elect to use a separately NFS-mounted filesystem for `/usr' with your diskless setup, make sure the "./usr" base files in base55.tgz end up in the correct location. One way to do this is to temporarily use a loopback mount on the server, re-routing /usr to your server's exported OpenBSD "/usr" directory. Also put the kernel and the install/upgrade scripts into the root directory. A few configuration files need to be edited: /etc/hosts Add the IP addresses of both server and client. /etc/myname This files contains the client's hostname; use the same name as in /etc/hosts. /etc/fstab Enter the entries for the remotely mounted filesystems. For example: server:/export/root/client / nfs rw 0 0 server:/export/exec/mvme88k.OpenBSD /usr nfs rw 0 0 Now you must populate the `/dev' directory for your client. If the server does not run OpenBSD you might save the MAKEDEV output: eo=echo ksh MAKEDEV all > all.sh and then tailor it for your server operating system before running it. Note that MAKEDEV is written specifically for ksh, and may not work on any other Bourne shell. There will be error messages about unknown users and groups. These errors are inconsequential for the purpose of installing OpenBSD. However, you may want to correct them if you plan to use the diskless setup regularly. In that case, you may re-run MAKEDEV on your OpenBSD machine once it has booted. Preparing an unattended installation of OpenBSD: ------------------------------------------------ If the installation system detects that it booted from the network, and isn't interrupted within 5 seconds, it attempts a fully-automatic installation. In this mode the installer runs dhclient(8) on the network interface the system booted from, or in case of multiple interfaces it will ask which one to use. Upon success it retrieves a response file via HTTP. The "next-server" DHCP option specifies the hostname part of the URL, as in "http:///install.conf". The "filename" DHCP parameter specifies the installer mode, e.g. "auto_install". On architectures where this parameter is used for netbooting, create a symbolic link named "auto_install" pointing to the boot program. The response file contains lines with key/value pairs separated by an equals sign '=', where the key is a non-ambiguous part (up to the question mark) of the installer question, consisting of whitespace separated words. The value is what would have been entered at the interactive prompt. Empty lines and lines beginning with a '#' character are ignored. The installer uses default answers in case of missing answers. Here is a response file example that uses a hashed password (see encrypt(1) for more details) for root and a public ssh key for the user that is created during the installation. System hostname = openbsd Password for root = $2a$14$Z4xRMg8vDpgYH...GVot3ySoj8yby Setup a user = puffy Password for user = ************* Public ssh key for user = ssh-rsa AAAAB3...RVtZJL puffy@ai What timezone are you in = Europe/Stockholm Location of sets = http Server = ftp.eu.openbsd.org The "System hostname" key above matches the following full question asked during an interactive installation: System hostname? (short form, e.g. 'foo') While the installation is in progress the installer writes all output to the file /ai.log, which is available as mail on the freshly installed system after the initial reboot. If the installation is successful the system will reboot automatically; otherwise, you will be dropped back into the shell where you can look at the /ai.log file or try again. Upgrading a previously-installed OpenBSD System: ------------------------------------------------ Warning! Upgrades to OpenBSD 5.5 are currently only supported from the immediately previous release. The upgrade process will also work with older releases, but might not execute some migration tasks that would be necessary for a proper upgrade. The best solution, whenever possible, is to backup your data and reinstall from scratch. As a minimum, if the toolchain (the ``comp'' set) was installed, you should remove all files within /usr/include before attempting to upgrade. To upgrade OpenBSD 5.5 from a previous version, start with the general instructions in the section "Installing OpenBSD". Boot from an installation tape, or bsd.rd over the network. When prompted, select the (U)pgrade option rather than the (I)nstall option at the prompt in the install process. You will be presented with a welcome message and asked if you really wish to upgrade. The upgrade script will ask you for the existing root partition, and will use the existing filesystems defined in /etc/fstab to install the new system in. It will also use your existing network parameters. From then, the upgrade procedure is very close to the installation procedure described earlier in this document. Note that the upgrade procedure will not let you pick neither the ``etc55.tgz'' nor the ``xetc55.tgz'' sets, so as to preserve your files in `/etc' which you are likely to have customized since a previous installation. However, it is strongly advised that you unpack the etc55.tgz and xetc55.tgz sets in a temporary directory and merge changes by hand, or with the help of the sysmerge(8) helper script, since all components of your system may not function correctly until your files in `/etc' are updated. Getting source code for your OpenBSD System: -------------------------------------------- Now that your OpenBSD system is up and running, you probably want to get access to source code so that you can recompile pieces of the system. A few methods are provided. If you have an OpenBSD CD-ROM, the source code is provided. Otherwise, you can get the pieces over the Internet using anonymous CVS, CVSync or FTP. For more information, see http://www.OpenBSD.org/anoncvs.html http://www.OpenBSD.org/cvsync.html http://www.OpenBSD.org/ftp.html Using online OpenBSD documentation: ----------------------------------- Documentation is available if you first install the manual pages distribution set. Traditionally, the UN*X "man pages" (documentation) are denoted by 'name(section)'. Some examples of this are intro(1), man(1), apropos(1), passwd(1), passwd(5) and afterboot(8). The section numbers group the topics into several categories, but three are of primary interest: user commands are in section 1, file formats are in section 5, and administrative information is in section 8. The 'man' command is used to view the documentation on a topic, and is started by entering 'man [section] topic'. The brackets [] around the section should not be entered, but rather indicate that the section is optional. If you don't ask for a particular section, the topic with the least-numbered section name will be displayed. For instance, after logging in, enter man passwd to read the documentation for passwd(1). To view the documentation for passwd(5), enter man 5 passwd instead. If you are unsure of what man page you are looking for, enter apropos subject-word where "subject-word" is your topic of interest; a list of possibly related man pages will be displayed. Adding third party software; ``packages'' and ``ports'': -------------------------------------------------------- As complete as your OpenBSD system is, you may want to add any of several excellent third party software applications. There are several ways to do this. You can: 1) Use the OpenBSD ``package'' collection to grab a pre-compiled and tested version of the application for your hardware. 2) Use the OpenBSD ``ports'' collection to automatically get any needed source file, apply any required patches, create the application, and install it for you. 3) Obtain the source code and build the application based upon whatever installation procedures are provided with the application. If you purchased the OpenBSD CD-ROM set you already have a few popular ``packages'', and the ``ports'' collection. Instructions for installing applications from the various sources using the different installation methods follow. You should also refer to the packages(7) manual page. Installing applications from the CD-ROM package collection: The OpenBSD CD-ROM ships with the most commonly installed third-party applications pre-built for various hardware architectures. Limited disk space on the CD-ROM unfortunately limits the number of such packages. Check the directory 5.5/packages/m88k to see which packages are available for your hardware architecture. That directory will be on the same CD-ROM containing the OS installation files for your architecture. To install one or more of these packages you must: 1) become the superuser (root). 2) mount the appropriate CD-ROM. 3) use the ``pkg_add'' command to install the software. Example (in which we use su(1) to get superuser privileges, thus you have to be in group "wheel", see the manual page for su(1)). $ su Password: # mkdir -p /cdrom # mount /dev/cd0a /cdrom # pkg_add /cdrom/5.5/packages/m88k/ # # umount /cdrom Package names are usually the application name and version with .tgz appended, e.g. bzip2-1.0.6p0.tgz Installing applications from the ftp.OpenBSD.org package collection: All available packages for your architecture have been placed on ftp.OpenBSD.org in the directory pub/OpenBSD/5.5/packages/m88k/ You may want to peruse this to see what packages are available. The packages are also on the OpenBSD FTP mirror sites. See http://www.OpenBSD.org/ftp.html for a list of current FTP mirror sites. Installation of a package is very easy. 1) become the superuser (root) 2) use the ``pkg_add'' command to install the software ``pkg_add'' is smart enough to know how to download the software from the OpenBSD FTP server. Example: $ su Password: # pkg_add \ ftp://ftp.OpenBSD.org/pub/OpenBSD/5.5/packages/m88k/emacs-21.4p23.tgz Installing applications from the CD-ROM ports collection: The CD-ROM ``ports'' collection is a set of Makefiles, patches, and other files used to control the building and installation of an application from source files. Creating an application from sources can require a lot of disk space, sometimes 50 megabytes or more. The first step is to determine which of your disks has enough room. Once you've made this determination, read the file PORTS located on the CD-ROM which contains the ports tree. To build an application you must: 1) become the superuser (root) 2) have network access, or obtain the actual source files by some other means. 3) cd to the ports directory containing the port you wish to build. To build samba, for example, where you'd previously copied the ports files into the /usr/ports directory: cd /usr/ports/net/samba 4) make 5) make install 6) make clean Installing applications from the OpenBSD ports collection: See http://www.OpenBSD.org/faq/ports/ports.html for current instructions on obtaining and installing OpenBSD ports. You should also refer to the ports(7) manual page. Installing other applications: If an OpenBSD package or port does not exist for an application you're pretty much on your own. The first thing to do is ask if anyone is working on a port -- there may be one in progress. If no such port exists, you might want to look at the FreeBSD ports or NetBSD pkgsrc for inspiration. If you can't find an existing port, try to make your own and feed it back to OpenBSD. That's how our ports collection grows. Some details can be found in the OpenBSD Porter's Handbook at http://www.openbsd.org/faq/ports/ with more help coming from the mailing list, . Administrivia: -------------- There are various mailing lists available via the mailing list server at . To get help on using the mailing list server, send mail to that address with an empty body, and it will reply with instructions. More information about the various OpenBSD mailing list and proper netiquette is available at http://www.OpenBSD.org/mail.html To report bugs, use the 'sendbug' command shipped with OpenBSD, and fill in as much information about the problem as you can. Good bug reports include lots of details. Additionally, bug reports can be sent by mail to: bugs@OpenBSD.org As a favor, please avoid mailing huge documents or files to the mailing lists. Instead, put the material you would have sent on a web server, then mail the appropriate list about it, or if you'd rather not do that, mail the list saying you'll send the data to those who want it.
